Abstract：

In　this　work,　we　investigated　the　magnetic　annihilation　and　reconnection　and　the　resulted　hot　electron　acceleration　driven　by　double-beam　intense　laser　pulses　in　two-layer　near　critical　density　(NCD)　plasma　target.　The　results　are　obtained　by　performing　two-dimensional　(2D)　particle-in-cell　(PIC)　simulations.　It　is　found　that　a　quasi-mono-energetic　peak　can　be　formed　in　the　energy　spectrum　of　electrons　accelerated　by　the　process　of　magnetic　field　annihilation　(MA)　at　cutoff　energy.　Electron　spectra　feature　depends　on　the　length　of　the　second　low-density　layer.　This　suggests　that　the　process　of　relativistic　magnetic　annihilation　may　be　controlled　in　experiments　by　target　design.　　©　2024　World　Scientific　Publishing　Company.
